I've a fujitsu lifebook S7220, it's been a while since i try to configure it to use a dual head with centos 5.4 x86_64. Everytime I try, the xserver crash... I've got an intel chipset mobile 4 serie (GMA 4500MHD, if I recall good!)

When I do an lspci -v i've got these :

00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07) (prog-if 00 [VGA controller])

My question is, anyone already got this problem and how did you fix it? Thank you for your answer!
